Uma Thurman

Don't be a square, it's time to celebrate Pulp Fiction's 20th anniversary. Quentin Tarantino's frenzied, gory and utterly unique cult masterpiece still delights fans two decades after its release – but would the film hold as much weight if rom-com staple Meg Ryan played Mia Wallace instead of Uma Thurman?

Shia LaBeouf's bizarre behavior in Germany over the weekend left some wondering if there is cause for concern.

The actor – who's promoting his new film, Nymphomaniac, at the Berlin International Film Festival – arrived sporting a shaved-down tooth and disheveled appearance for the cast panel, answering only one question before quickly exiting the room.

When asked how it felt to be in a movie with such explicit sex scenes, LaBeouf took a drink of water and said, "When the seagulls follow the trawler, it's because they think sardines will be thrown into the sea."

How else to react to the provocative posters for Nymphomaniac – the upcoming film from Danish director Lars von Trier – that capture each of the movie's stars in a seemingly heightened state of arousal.

Set for a world premiere in Denmark on Christmas Day, the controversial NC-17 film follows the erotic life of a woman, Joe (played by Charlotte Gainsbourg) from birth to the age of 50, and stars Shia LaBeouf, Uma Thurman, Christian Slater and Jamie Bell, among others.

Biel, dressed in a navy tank top and white pants, had a blast rocking out in the VIP mezzanine area during the show, which was sponsored by MasterCard. "She knew all the words to his songs and was dancing the whole time," an onlooker tells PEOPLE. "She looked very proud."
